Application tiled July 16, 1913. Serial No. 273,355'.

To all whom it may concernl Be it known that i, (herinnert C. Roenes,

e citizen of the United States, residing et by ineens of which the explosive charge the compression chamber oi' the engine Wiii be proportioinitely reflue/ii or increeseci, to in n single engine produce n striictnre espe.- ble or varying; horse power, thus' providing ineens whereby the 'nel consumption Wii he regulated entirely by the horse power und so that e great econonr;r in the use of: inel will result.

1i further object oi? the present invention, is the provision et' a. meek '.jnifsin for simcitnneonsly operating :i compression chamber regulating' .means find the throw oi' the in Luke -vnlre so that a proportionate ernennt of charge is admitted according to the limited or increased voiinne of the cyiinder.

With the foregoing end other objects 'in View which will appear es the description proceeds, the invention resides in the combination sind arrangement of ports and in the details of construction hereineiiter describeri und claimed, it being understood that changes in :the precise embodiment of the invention herein disclosecl cnn be inefie `within the scope of what is cleinieii without ieiierringj to the drawings7 the nnnierei 1' designates the base of the engine which nos mounted therein c crank shaft 2, to which. connected. the piston roei 3. lcrrieii oy the piston roti 3 is the usuel power piston mounted for reciprocetion Within the cylin- (ier 5, the cylinder lacing; divided ley the ciotteci iine into the compression cheminer "Z eine, on intello valve 87 which is indicntive or any :torni oi'r' valve, proviolech end in 'the present instance it is provicie; with the i veli/e stern 9, the spring l0 ot Awhich norH :nelly holiis the valve sented. rhis stem is opercteci through :any mechanism from tire crnnir streift 2 to loe niechenicnili; opened to siiinit of the change of ciirhnretefi eir et the `,roper time within the cylinder oi the en gine. lin the iower emi of the enero er in .any convenient 'port ther-emc is provificci the tapered slot ii into Wliich is nfiiip'te to fit the siidinc Wcfigge i2, said 'Wedge i2 being; disposed for siiding; movement in the brackets 13, the operation ofso-iii Wedge he-v ine: such as to, through the sint il, regniate the lnoif'einent of the stein 9 end conse qnentiy the reletive increment of the Veive 8 from its sect, i i

The operating stein i8 of the member is inonnteii for slifiing finti rot-ery move rent in the stniing boi: i9 disposed conceniioelly o lf the-heed of the cyiinder 5 andnpon the upper end the stern is iieieoi c pinion 20, which shown is in ines'i et oil times with the teeth of the horizont-eli? disposed reci: This reci; is monnteii for reieiproceiion within. the supports Q1 inounteii upon the exterior of the heed of the engine and carrying the ioopeoi 'portion 23 which' is conneflfteii to the operating and controliingij iever This lever has its flower end pivoied in the lug 25 carried exterior of the bese of the engine and carries,

the adjustable bolt held cie'vice or connection 2G, which is nivoteliy connected. et one enti to the l2 and through the iever 2s: rn. i'\ gir c B o* L nnismicc. n,Y .ign ky uns ineens the Weflgc insgT he edgnstecl at will. this ineens, Wni ce seen thet when the iever 2li is il ereiecl that botti' the rock 22 end tno weee, 32 mii be opeieteci simnitcnconsir cnc so; o n will es the compression area-7 oi the engine and at the same time permit of the increase or decrease in the relative movement of the v.va1ve.8. i These elements are so constructed, `rv5v that the proper proportion of oarbureted air E is admittedinto the cylinder of the engine relatively to the oompression chamber or space 7i, sothvat with this structure an engine l lf-may be economically run lat an exceedingly `10 .low or a. comparatively high horse power.

. What is lclaimed is:

` An explosive engine, having a cylinder, an intake valve,.a slidable and rotatable "compression chamber regulating member 'IQ mounted in the head of the cylinder, a stem ldisposed concentric'ally of and through the cylinder head and carrying the member, :i

pinion carried by the stem, a toothed rack moines mounted upon. the cylinder and disposed to coact with the slot of the stem to regulate the throw of the valve, and a lever connectpression chamber regulating member and wedge are operated simultaneously.

In testimony that I claim the foregoing as inthe presence of two witnesses. l l l CLARENCE C. ROGERS.'
